Wordpress Custom Posts -> Publish To Facebook Wall

Hey Here's the deal. I have a wordpress blog that has a scraping php script installed. This script adds posts to the wordpress database twice a day. I need these posts to be PUBLISHED to a Facebook Page Wall. THINGS TO KEEP IN MIND: 1. The script RE-MAKES all of the posts every day. (It deletes all old posts, then adds new ones instantly) This means that if you just set it to Publish to facebook any new post, it will SPAM THE WALL! So you have to make it ONLY PUBLISH posts that are new. Like, if post name "BLUE TANGO" has been published before to facebook, it will NEVER be published to Facebook again (because Blue Tango will be deleted/added perhaps twice a day) 2. The posts are Custom Posts (WP plugin) 3. The posts are being directly entered into the database, and therefor wordpress does not recognize them as new. 4. I tried using the Wordbooker plugin, and it doesn't publish any of the posts to facebook until i set it to "Draft" then publish it again. You can use wordbooker if u want and somehow customize it. I know Wordbooker can be configured to work with custom posts, but there is still the issue of the posts being re-made twice a day ( = spammed wall) Anything really.. just aslong it gets the job done Tell me HOW you would do this project! I'll send you details in PM
